PIPE CONNECTION.

Specification of Letters Patent.

Patented Nov. 5, 1918.

Application led November 21, 1917. Serial No. 203,133.

To all whom t may concern:

Be it known that I, JOHN PiLLiG, aI citizen of the United States,residing at Amsterdam, county of Montgomery, and State of New York, haveinvented certain new and useful Improvements in Pipe Connections, ofwhich the following is a specification. l,

Reference may be had to the accompanying drawings, and the referencecharacters marked thereon, which form a part of this specification.Similar characters refer to similar pai-ts in the several figurestherein.

This invention relates to means for coupling together the neighboringends of two pipes arranged end to end.

The principal object of the invention is to facilitate connecting anddisconnecting said pipes.

Other objects will appear in connection with the following description.

Figure 1 is a View in side elevation of aI pipe-connection embodying myinvention.

Fig. 2 is a view in side'elevation of the longer clamping-memberdetached.

Fig. 3 is a view in side elevation of one of the shorterclamping-members, adapted to coperate with one end of' the longerclamping-member.

Fig. 4 is a view in side elevation of the other shorter clamping-member,adapted to coperate with the other end of said longer clamping-member.

Fig. 5 is aI bottom plan view of the longer clamping-member and theshorter clampingmember shown in Fig. 3, slightly separated from eachother.

Fig. 6 is a central longitudinal section of the pipe-connection taken onthe broken j line 6-6 in Fig. 1.

Referring to the drawings wherein the invention is shown in preferredform, 1 is a rubber sleeve, which incloses a nipple, 2, having a flange,3, engaged by a couplingsleeve, 4, which is adapted to screw on to thenipple of a beer-barrel or the like, not shown.

A rubber-washer, 5, within the sleeve, 4, serves to make a ti htconnection with said nipple on the beerarrel.

The lower end of the rubber sleeve. 1, is clamped upon the nipple, 2, bytwo semicylindrical clamping-members, 6 and 7, drawn together by screws,8, inserted through ears, 9, on the clamping-members.

The clamping-member, 6, is elongated to extend along one side oftherubber sleeve, 1, past the joint between the abutting ends of saidnipple, 2, and a' pipe, 12, inserted within the other end of the rubbersleeve, 1.

The upper end of the clamping-member 6 is tapered and screw-threaded asat 10;- and, disposed opposite said tapered screw-threaded portion, andon the opposite side of Said rubber sleeve is a similarly taperedscrewthreaded shorter clamping-inember, 11, said tapered screw-threadedclamping-members being adapted to be drawn together by means of a nut,13, fitting their screwthreaded portions.

The pipe, 12, may be a beer-pipe leading to a bar-faucet, not shown.

The nipple, 2, and pipe,` 12, however, may be any pipes which it isdesired to connect together.

The clamping-member, 11, has a leg, 14, which projects downward througha groove, 15, in the clamping-member, 7, and has a lug, 16, whichengages a notch, 17, in the lower end of said claniping-member, 7,whereby the clamping-member, 11, is keyed to the clamping-member, 7

By loosening the nut,-13, the pipe, 12, can be inserted within, orremoved from, the

rubber sleeve, 1, and by tightening the nut,

be clamped 1 3, the rubber sleeve, tightly upon the pipe, joint.

1, can 12, to make a tight The pipe, 12, can thus be connected and/disconnected from the nipple. or pipe, 2, without disturbing theconnection between the nipple or pipe, 2, and the rubber sleeve, 1.

In like manner, the nipple, 2, can be disconnected from the pipe, 12,and from the rubber sleeve, 1, by loosening the screws, 8, withoutinterfering with the connection between the rubber sleeve, 1, and thepipe, 12.

While I have described the sleeve, 1, as made of rubber, it may be madeof any matweensaid pipe-ends; a second substantially semicylindricalclamping-member engageable with: the opposite side of saidcompresvterial which can be suiiciently compressed sible sleevecoperative with said rst-men.- tioned clamping-member on one side ofsaid joint, said clamping-members being similarly tapered andscrew-threaded; a nut engageable with the tapered screw -threadedportions ofV said clamping-members; and a third clampin -memberengageable with said compressi 1e sleeve cooperative with saidrst-mentioned clamping-member on the other side of said joint. l

2. In a pipe-conneetlon and 1n coinbmation, a oompressible sleeveadapted to incluse the abutting ends of two pipes arranged end to end; asubstantially semicylindrial clamping-member extendmg along oneslde ofsaid compressible sleeve past the joint between said pipe-ends; andseparate substantially semi-cylindrical clamping-members lengageablewith. the opposite side of said compressible sleeve, one on one side andthe other on the opposite side of, said. joint between said ipe-ends.

3. n a pipe-connection and 1n combination, a compressible sleeve adaptedt0 inclose.

the abutting sndsfdf twfY pipes end to end; a-'substantiallysemieylindneal' clamping-member extending along one side of saidcompressible sleeve past the joint between said pige-ends; aclamping-member operative wit lng-member onone side of said joint; meansfor drawing said clampin -members Itogether to compress said s eeve; athird clamping-member, separate to said second-mentioned clamping-mem rengageable. with said @posits side of sai compressiblfe sleeve,eoperative with said first-mentioned clamping-member 'on the other sideof said joint, said first-mentioned and said last-mentionedclamping-members being tapered and screw-threaded; `and va nut engagingsaid tapered screw-threaded portions of said two last-mentioned clampin-membera n testimony whereof, I have hereunto 'set my hand this lth'dayof November, 1917.
